New transmitter identification mechanism for DVB-T2

In the DVB-T2 digital terrestrial television standard a transmitter signature can be included in order to provide a unique identification to each of the transmitters in the network. This feature is optional and it can be exploited for many other applications. For instance, it is a very valuable tool for broadcasters intending to bring new a single frequency network onto air or troubleshooting a network that was already working. In the DVB-T2 physical layer standard, a couple of options are provided, and the network operators are the ones that should select the solution that copes better with their particular requirements. In this work, the main characteristics and drawbacks of the already existing solutions are studied comprehensively, and afterwards, a new transmitter identification mechanism which overcomes the previously identified challenges is presented. The proposed solution is based on the direct sequence spread spectrum modulation. The presented technical solution will be backwards compatible with current receivers, and what is more, its features will make easier the implementation of new application scenarios, such as WIB.
